In order to do Sand Casting one needs a proper "Flask" to contain the sand mold so you can pour your metal. This instructable shows you exactly how I make mine and they work great. Please watch the entire video to see how mine are constructed and you can make your own version at home using the tools you have on hand. Wood, wood glue, some screws and you are off and running. A hand saw will work fine but a table saw will make ya a nicer Flask in my opinion!
If you have any questions about the process feel free to ask. Watch the video for all the steps involved in bringing the project to completion. Please be sure and check out all my metal casting instructables I have posted. Thanks for Watching!
